Vladimir Oltean says: ==================== PTP_CLK pin configuration for SJA1105 DSA driver This series adds support for the PTP_CLK pin on SJA1105 to be configured via the PTP subsystem, in the "periodic output" and "external timestamp input" modes. ==================== Signed-off-by: David S.

2020-03-23net: dsa: sja1105: configure the PTP_CLK pin as EXT_TS or PER_OUTVladimir Oltean
The SJA1105 switch family has a PTP_CLK pin which emits a signal with fixed 50% duty cycle, but variable frequency and programmable start time. On the second generation (P/Q/R/S) switches, this pin supports even more functionality. The use case described by the hardware documents talks about synchronization via oneshot pulses: given 2 sja1105 switches, arbitrarily designated as a master and a slave, the master emits a single pulse on PTP_CLK, while the slave is configured to timestamp this pulse received on its PTP_CLK pin (which must obviously be configured as input). The difference between the timestamps then exactly becomes the slave offset to the master. The only trouble with the above is that the hardware is very much tied into this use case only, and not very generic beyond that: - When emitting a oneshot pulse, instead of being told when to emit it, the switch just does it "now" and tells you later what time it was, via the PTPSYNCTS register. [ Incidentally, this is the same register that the slave uses to collect the ext_ts timestamp from, too. ] - On the sync slave, there is no interrupt mechanism on reception of a new extts, and no FIFO to buffer them, because in the foreseen use case, software is in control of both the master and the slave pins, so it "knows" when there's something to collect. These 2 problems mean that: - We don't support (at least yet) the quirky oneshot mode exposed by the hardware, just normal periodic output. - We abuse the hardware a little bit when we expose generic extts. Because there's no interrupt mechanism, we need to poll at double the frequency we expect to receive a pulse. Currently that means a non-configurable "twice a second".

2020-03-23net: dsa: sja1105: make the AVB table dynamically reconfigurableVladimir Oltean
The AVB table contains the CAS_MASTER field (to be added in the next patch) which decides the direction of the PTP_CLK pin. Reconfiguring this field dynamically is highly preferable to having to reset the switch and upload a new static configuration, so we add support for exactly that.

2020-03-23net: dsa: sja1105: make future_base_time a common helperVladimir Oltean
Because the PTP_CLK pin starts toggling only at a time higher than the current PTP clock, this helper from the time-aware shaper code comes in handy here as well. We'll use it to transform generic user input for the perout request into valid input for the sja1105 hardware. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

2020-03-23net: dsa: sja1105: unconditionally set DESTMETA and SRCMETA in AVB tableVladimir Oltean
These fields configure the destination and source MAC address that the switch will put in the Ethernet frames sent towards the CPU port that contain RX timestamps for PTP. These fields do not enable the feature itself, that is configured via SEND_META0 and SEND_META1 in the General Params table. The implication of this patch is that the AVB Params table will always be present in the static config. Which doesn't really hurt. This is needed because in a future patch, we will add another field from this table, CAS_MASTER, for configuring the PTP_CLK pin function. That can be configured irrespective of whether RX timestamping is enabled or not, so always having this table present is going to simplify things a bit.

No functional changes intended. Policers are going to be added as attributes of packet trap groups, which are entities used to aggregate logically related packet traps. This will allow users, for example, to limit all the packets that encountered an exception during routing to 10Kpps. However, currently, device drivers register their packet trap groups implicitly when they register their packet traps via devlink_traps_register(). This makes it difficult to pass additional attributes for the groups. For example, the policer bound to the group. Therefore, this patch set converts device drivers to explicitly register their packet trap groups. This will later allow these drivers to register the group with additional attributes, if any. ==================== Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-03-23netlink: check for null extack in cookie helpersMichal Kubecek
Unlike NL_SET_ERR_* macros, nl_set_extack_cookie_u64() and nl_set_extack_cookie_u32() helpers do not check extack argument for null and neither do their callers, as syzbot recently discovered for ethnl_parse_header(). Instead of fixing the callers and leaving the trap in place, add check of null extack to both helpers to make them consistent with NL_SET_ERR_* macros. v2: drop incorrect second Fixes tag Fixes: 2363d73a2f3e ("ethtool: reject unrecognized request flags") Reported-by: syzbot+258a9089477493cea67b@syzkaller.appspotmail.com Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

Sunil Goutham says: ==================== octeontx2-vf: Add network driver for virtual function This patch series adds network driver for the virtual functions of OcteonTX2 SOC's resource virtualization unit (RVU). Changes from v3: * Removed missed out EXPORT symbols in VF driver. Changes from v2: * Removed Copyright license text. * Removed wrapper fn()s around mutex_lock and unlock. * Got rid of using macro with 'return'. * Removed __weak fn()s. - Sugested by Leon Romanovsky and Andrew Lunn Changes from v1: * Removed driver version and fixed authorship * Removed driver version and fixed authorship in the already upstreamed AF, PF drivers. * Removed unnecessary checks in sriov_enable and xmit fn()s. * Removed WQ_MEM_RECLAIM flag while creating workqueue. * Added lock in tx_timeout task. * Added 'supported_coalesce_params' in ethtool ops. * Minor other cleanups. - Sugested by Jakub Kicinski ==================== Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-03-23octeontx2-pf: Cleanup all receive buffers in SG descriptorGeetha sowjanya
With MTU sized receive buffers it is not expected to have CQE_RX with multiple receive buffer pointers. But since same physcial link is shared by PF and it's VFs, the max receive packet configured at link could be morethan MTU. Hence there is a chance of receiving plts morethan MTU which then gets DMA'ed into multiple buffers and notified in a single CQE_RX. This patch treats such pkts as errors and frees up receive buffers pointers back to hardware. Also on the transmit side this patch sets SMQ MAXLEN to max value to avoid HW length errors for the packets whose size > MTU, eg due to path MTU.
